aeoeaoi;

To all w/wm 2v may concern:

Be it known that we, Howano F. MARs'roN and JOHN J. UComvnnn, citizens of the United States, residing at Dayton, Ohio,

have invented certain new and useful Im- 1 provements in VVindow-Envelops, of which the following is a full, clear, and'exact description.

This invention relates to certain new and useful improvements in envelops of the type known as window or outlook envelops.

. One objectof this invention is to so fabri cate the envelop blank that the amount of paper wasted is minimized. In this way the price of the envelopis reduced.

Another object of our invention is to place I the patch in a novel position on the blank which position facilitates the applyingof the patch. I

Another object of our invention is to produce an envelop in which the front of the envelop is open while the inclosure is being inserted so that the inscription on the inclosure will be visible to the person inserting the inclosure in the envelop. With this construction, the person inserting the inclosure is less liable to make mistakes such as placing the letter or the inclosure in the envelop upside down or wrong side forward.

In the drawings: Figure 1 Shows the envelop blank with the transparent patch at tached, and with the flaps gummed and ready'for folding. Fig. 2 shows the envelop folded and ready for the inclosure. Fig. 3 shows the envelop with the inclosure therein, and .with the seal flap folded down.

The-body'portion of the envelop is. made of opaque material. This opaque portion of the blank comprises the blank shown at and defined by fold lines 11, 12, 13 and 14'; second, the side flaps 15 and 16 defined by fold lines 11, 13 and margins 17 and 19;

third, the body flap defined by fold line' 14 and margin line 24; fourth, the seal lap 20 defined by fold. line 12 and. margin line 18. The seal flap is gummod as shown by the shaded gum strips 33. The bottom flap is also gummed as shown by the shaded gum spots 34. It will be understood that if desired the gum spots 34 can be placed on the side flaps 15 and 16 instead of on the bottom When this is done, the side flaps flap 25. are first folded and the bottom flap is folded -over them instead of vice versa as is the case with the construction illustrated in Figs. 1

and 2. The seal flap 2U, defined by lines 21,

18, 23, and fold line 12, has a window aperture out therein. This aperture 30 is defined by the line 31. Over this aperture is placed a transparent patch 27. Transparent patch 27 is secured by gum to theborder of the aperture 30. The transparent patch terminates at the line 32 as shown in Figs. 1

v and 2. It will be understood that this patch 27 is applied over the window before the envelop is folded and before the gum strip 33 is applied to the seal flap 20,

In making the envelop the body portion is cut to the shape shown in Fig. 1, and the 1 patch 27 is applied as previously explained.

Then gum is applied to the blank at the points indicated by the shaded portions 33 and 34C. Thereafter, the side flaps 15 and 16 are infolded, and finally the bottom flap25 is folded over and engaged by the gum spots 34 to the bottoms of the side flaps.

The completed envelop ready for the in:

.closure is shown in Fig. 2. In this figure 'it will be seen that the side flaps 15 and 16,

when infolded, form edge supports for the inclosure while the bottom flap 25 forms a bottom support for the said inclosure. Since the side flaps 15 and 16, when infolded, terminate at a distance from each other, the front of the envelop is left entirely open with the exception of a small part about the border. This allows the person inserting the inclosure in the envelop to at all 'times see the inscription on the inclosure,

and in this way prevent mistakes in placing the inclosure in the envelop. After the inclosure is correctly inserted in the envelop,

art. What we claim as our invention is particularly pointed out in the appended claims.

We claim: 1. An envelop comprising in combination,

an opaque body portion comprising a back 1 portion; side flaps extending therefrom; a

bottom flap; a seal flap. said seal flap having a window aperture therein; and a transparent sheet secured to the seal flap and covering the aforesaid aperture, the said'seal flap engaging the side and bottom flaps and forming the front of the envelop when sealed.

2. An envelop comprising in combination, an opaque back portion; side and bottom flaps extending therefrom, said flaps engaging each other and thereby forming edge supports for the inclosure; a seal flap engaging said side and bottom flaps to close the envelop, said seal flap having a window aperture therein; a transparent sheet engaged by the seal flap and covering the aforesaid aperture.

3. An envelop comprising in combination, an opaque back portion; a bottom flap; a pair of side flaps infolded and engagingthe bottom flap at their ends, said side flaps, when infolded,'being spaced from each other whereby the inscription on the inclosure is visible when theisaid inclosure is being inserted in the envelop; and a seal flap folding over and engaging the said side flaps and the bottom flap and thereby forming the front of the envelop, the said seal flap having a Window aperture therein.

4. An envelop comprising in combination, an opaque back portion; a bottom flap, a pair of side flaps infolding and engaging the bottom flap their ends; when infolded, being spaced from each other whereby the inscription on an inclosure is visible when the said inclosure is being inserted in the envelop; and a seal flap folded over and engaging the said side flaps and the bottom flap and thereby forming the front of the elfivelop, said seal flap having a window aperti re therein; and a transparent sheet secured; to the seal flap and covering the aperture;

. engaging each other and forming an side flaps when 5. An envelop comprising in combination, an opaque back portion; a bottom flap; a pair of side flaps, said side and bottom flaps envelop pocket with a substantial open face the inscription on the inclosure will be Visible while the inclosure is being inserted in the envelop pocket, a seal flap folded over and engaging the side flaps and bottom flaps, and thereby forming the front of the envelop, said flaps having a therein, and a transparent patch covering the aforesaid aperture.

An envelop comprising, in combination, an opaque back portion, an opaque bottom flap integral with and extending from the back portion, a pair of opaque side flaps integral with the back portion infolding and engaging the bottom flap at their ends, said infolded being spaced from each other whereby the inscription on the inclosure is,visible when the said inclosure is being inserted in the envelop; an opaque seal flap integral with the back portion and perforated with a window aperture, said seal flap being adapted to fold over and engage the side and bottom flaps and thereby form the front of an envelop, and a transparent sheet covering said window and secured by gum to the borders of the window.

In testimony whereof we afiix our signatures in the presence of two subscribing witnesses.
